Rulings
- Midnight Arsonist's triggered ability can't target artifacts that have either activated or triggered mana abilities. An activated mana ability is one that could add mana as it resolves, doesn't have a target, and isn't a loyalty ability. A triggered mana ability is one that could add mana as it resolves and triggers based on an activated mana ability.
